Variability and evolution in model-based engineering of embedded systems

In this paper, we report on techniques for variability and evolution in Model-based Engineering of Embedded Systems. The techniques are based on an integration of domain-specific languages for embedded systems with model-driven techniques for Software Product Lines. In particular, we discuss (1) product configuration with interactive tools, (2) product derivation with model transformations, and (3) first steps towards feature-oriented evolution planning.
